They probably just clicked because they wanted to see what you guys had made, since consent is present in the rest of the game. Personally, I wasn't expecting he would touch her while she was sleeping, and definitely not go as far as raping her while she was unconscious and then celebrate that he was lucky he wasn't caught.
If you don't think the scene is offensive, but recognize it is rape, maybe you could add a penalty to a player who chooses to rape instead of just covering her up, for example, which is a reasonable option to add in my opinion.
